Problems solved by technology

[0002] In the vanadium-nitrogen alloy production line, the push plate was made of high-temperature-resistant imported materials from Japan. The push plate of this material has the characteristics of high strength and good wear resistance when it enters the high-temperature furnace, but its weakness is: Poor thermal conductivity, high propulsion resistance, easy adhesion at high temperature, short service life, generally no more than 2000 hours, resulting in high production costs

Abstract

The invention discloses a graphite push slab which consists of the following ingredients in proportion by weight: 82 percent to 88 percent of graphite, 10 percent to 15 percent of alundum powder and 2 percent to 3 percent of refractory mortar. The production method of the graphite push slab of the invention is that: the graphite, the alundum powder and the refractory mortar are selected and mixed at a mixture ratio, pressed into shapes and burned in a high temperature kiln at 1000 DEG C to 1200 DEG C. The push slab of the invention has small pushing resistance, good heat-conducting property, light weight and long service life and is high temperature resisting, non-adhesive, antiseptic and oxidation resisting.

Description

technical field [0001] The invention relates to an accessory of a kiln for producing a special steel additive vanadium-nitrogen alloy, in particular to a graphite push plate. Background technique [0002] In the vanadium-nitrogen alloy production line, the push plate was made of high-temperature-resistant imported materials from Japan. The push plate of this material has the characteristics of high strength and good wear resistance when it enters the high-temperature furnace, but its weakness is: Poor thermal conductivity, high propulsion resistance, easy adhesion at high temperature, and short service life, generally no more than 2000 hours, resulting in high production costs. Contents of the invention [0003] The object of the present invention is to provide a graphite push plate, which has a long service life on the one hand and reduces production costs, and on the other hand has good thermal conductivity and saves production energy. [0004] Technical solution of the...
